This sentence helped me to visualize what might be happening.
"Just as a grounded boat can float again when the weight of its cargo is removed, a glacier that loses ice weight can float over land where it used to stick. When this happens, the grounding line retreats inland. That exposes more of a glacier's underside to sea water, increasing the likelihood its melt rate will accelerate.
"
not clear from the article though, what do they think is causing the retreat?
Is it warming of ocean water, or we do not know yet?
